IMPROVEMENT iN SEEDING-MACHINES.

Speciiication forming part VofhLctiers RatentNO. 21,349, dated :August '31 155B.

To all whom 'it may concern:

Be it known that we, d. MGUORMICK, of Versailles, in the county of Woodford and State ot' Kentucky, and WV. 1t. BAKER, of `Boston, in the couutyof Suffolk and State of Massachusetts, have invented-anew and useful Improvement in Seeding Machines; and we vdo hereby declare that the following is a full, clear, and exact 'description of the same, reference being hadto the annexed drawings,

making a part of this specitication, in which- Figure 1 is a side view of a seeding-machine with our improvement attached to it. Fig. 2

is a detached end view of onri'mprovement, one

part being in section.

Similar letters of reference indicate correspending parts in the two figures. l This invention relates to a novel means employed for forming the drills or furrows and depositing the seed in the `ground, as hereinafter fully shown and described.

To enable those skilled inthe art to fully understand .and construct our invention, we

will proceed to.descrbe"it. 4

A represents an axle, and B B the wheels and O the thills or shafts which are attached to the axle. The back endspf the thills or shafts project beyond the back of the Vaxle and form beds forvsnpports D, on whichV a seed-box, E, is placed, said box being provided with-'any proper seed-distributing device. l

'lo the under side of the axle A the front tend of'a frame, E, is attached by joints a, said frame being allowedto work freely' up and,

down on said'joints. In the frame E a shaft,

F, is placed' transversely, and on this shaft two wheels, G (l, areplaced'and permanently secured. 'lhesewheels may be of4 concave or dish-form, and agshonlder, b, is formed in each wheel near its periphery, said shoulders being produced by having the concave or cavity ot' the wheels passjihorizontally inward parallel with the axle A a-short distance, as shown clearly in Fig. 2.?) The wheels G G are formed with sharp edges, both sides of the wheels near their periplieries being basiled. (See Fig. 2.) The wheelsG G may be made of cast or wrought metal, and of any suitable dimensions-probably wheels a 'foot and a half in diameter will be the size generally used.

To the under side of the frame E two plates or shares, H H, are attached. These plates orsharesare placed one by theconca've sideot each wheel G. The frontends ofthe plates or shares are rounded, and they fit within the shoulders b ot' the wheels, said shoulders serving as a protection or'guardito the plates. The back ends of' the plates are each curved alittle ont- Ward, so as to form a sort of mold-board, c, to make the necessary fnrrows. This is clearly shown` in Fig. 2. The back parts or ends of the plates or shares H do not tit within the Shouldersb of the wheels G. They'project outward a trifle from it. The plates or shares H are constructed ot' metal, either cast or wrou gh t, and the mold board c or` curved portions ot' the plates or shares H may be sufficiently `curved to turn over the earth or to merely into the spaces between the wheels and plates,

and the Wheels by their rotation, caused by the forward movement ot the machine, will discharge the seed out at the back part ot' the wheels, between thewheelsand plates or shares, the seed being deposited in the drills or furrows made by the penetration of the wheels Vinto theearth and the mold-hoardsc of the shares or plates H H'. v

' The wheels yGr will cnt through all trash-` such as sods, weeds, and the like-so that such substances will not obstruct in any degree the proper workingof the machine and obstaclessuch as stumps, stones, &c.-th at may lie in the path of the wheels are readily passed over in consequence ot' the free movement .ot the 4frame E.

We would remark that instead ot' having the wheels G G concave the plates or shares H may be thus made and the wheels Gr` be dat.

This plan, however, would be merely reversing the form of the parts. We would further remark that any number ot' wheels may be used on one machine, several frames E being attached to the axle A.

We do, not claim broadly the employment ot' l a hollow wheel for depositing the seed but, Having thus described our invention, what -we claim as new, and desire to secure by Letters Patent, is l -'Ilhe arrangement and combination of the rotating wheelG with the stationary plates or shares H, substantially as and for thc purpose herein shown and described.
